Bamo NivOil® / 12V DC Alarm System for Oil-Water SeparatorsIndonesia Industrial Parts

Overview

Bamo NivOil / 12V DC Alarm System designed for the monitoring of hydrocarbon fluids separators, the alarm device NIVOIL may be connected to 1, 2, or 3 sensors.

Hydrocarbon layer thickness sensor to detect when the maximum thickness is reached.
Overfill sensor to detect when the fluids are on the highest level.
Sludge layer sensor for alarming when maintenance is necessary.

The 3 sensors may be connected to any input of the alarm device NIVOIL. Any combination of the sensors can be wired. The instrument recognizes automatically the level sensor type. An LED indicates the sensor type on the diagram on the front board. The alarm device NIVOIL has a built-in buzzer; it is possible to disable its function.

Bamo NivOil Alarm System Features

Low power consumption – 10…27 V DC power supply input
Zone 0 ATEX certified (Zone 2 for the alarm device location)
Solar-powered or standard electric battery – Energy saving mode adjustable (control frequency adjustable from 6 min up to 9 days)
3 inputs, for any NIVOIL probes
Automatic recognition of type probe
3 relay outputs with audible alarm

Low power consumption

This model working with a 10 to 27 V DC power supply has low energy consumption. It is designed for the use of a solar-powered battery or any standard electric battery (consumption is 0.1 W – 12 V DC – with 3 sensors connected with one complete control cycle per hour).

Sleep mode

This mode is adjustable by modifying the frequency of the control cycle (from 6 minutes up to 9 days). A continuous control mode could be switched on when there is no limit on consumption.

ATEX certified

All the components are ATEX-certified. The sensors are for a location in zone 0 and the alarm device corresponds to a zone 2.
